double sided crown molding

Has anyone used the double sided crown molding? It supposedly makes it easier to get tighter miter joints because you cut it once then flip one piece over and, viola, perfect matched joint. I'd like to know if it works as advertised and would be good for an amateur.

I have used it before and didn't like it. Maybe because they purchased it a big box store. The problem I found is that the profiles are not a perfect match on each side. Customer prepainted one side only before I installed but I couldn't figure out why the corners would not match. I cut a couple of scarf joints and thats when I realized the problem...profile on the back side was 1/8" off from the profile on the front.

As for outside corners, you will rarely, if ever, find a perfect 90 degree corner. Sheetrock corner bead always adds thickness at the corner, in order to cover the fastening flanges. I've found that even after adding to the miter angle to compensate for this, the second cut always needs to be adjusted for perfection.

After looking at the double sided crown, there is very little material left to get a pin nail in the corners, not to mention limitted glue surface.
